What is the main cause of ionization of gases in the thermosphere?
Answer and explanation
Correct answer: High-energy radiation coming from the Sun
The correct answer is A because the thermosphere absorbs intense ultraviolet and X-ray radiation from the Sun. This radiation has enough energy to remove electrons from gas atoms, producing positively charged ions and free electrons. Evaporation, surface dust, and friction from mountain winds mainly affect lower atmospheric processes and cannot explain widespread ionization at thermospheric heights.
